JOYO Buffer Tuner Pedal Built-in Buffer with Accurate Tuning and LED Screen for Electric Bass Guitar Effects (Buffer Tune JF-19)

About this item Tuning Mode--JOYO JF-19 BUFFER TUNER gives you fast, accurate tuning and a multi-functional tuning tool in a single unit with 1 cent accuracy. In order to make the pedal work properly and quietly, JOYO 9V DC pedal power supply with noise reduction technology can be used Buffer Mode--Built-in analog BUFFER circuit preserves your tone through long cable runs and convoluted pedalboards, meanwhile, it features a independent buffer switch, you can switch between tuner and buffer when select the buffer mode Easy-to-read LED Screen--the big colorful LED screen enable you to read the tuning notes easily under any circumstances Compact Size with power source function--what makes this pedal unique is the DC Output Jack, you are able to power another pedal if you want, the current is the same as the input current Metal alloy case and precision components makes it solid, lightweight and portable

• If chain is simple, you can only enable "TRUE BYPASS" to use
• If cables are long or the number of pedals is ≥ 5, be sure to enable "BUFFER"
• Tuner/Buffer mode switching via footswitch (buffer remains active condition)
• Equipped with a 9V DC power output interface, which can power other guitar pedals
• It simplifies the pedalboard layout and reduces cable clutter
• Power supply:DC 9V is NOT included in the package.
• Please select JOYO original power supply or other reliable brands to reduce noise and damage
• Place the pedal at the very front of the signal chain (Guitar → JF-19 → other effects → amplifier) to maximize the buffer's tone-protecting effect
• TRUE BYPASS mode: For setups with < 3 pedals and cables < 2m (no significant tone loss) – only uses tuning; signal bypasses the buffer to avoid unnecessary compensation
• BUFFER mode: For cables > 3m or ≥ 3 pedals (high-frequency loss, muffled tone) – activates buffer compensation (restores high frequencies) + tuning to retain the guitar’s original tone
